Exodus 28:14-22

14and two chains of pure gold, twisted like cords; and you shall attach the corded chains to the settings. 15“You shall make a breastpiece of judgment, in skilled work. In the style of the ephod you shall make it—of gold, blue and purple and scarlet yarns, and fine twined linen shall you make it. 16It shall be square and doubled, a span its length and a span its breadth. 17You shall set in it four rows of stones. A row of sardius, topaz, and carbuncle shall be the first row; 18and the second row an emerald, a sapphire, and a diamond; 19and the third row a jacinth, an agate, and an amethyst; 20and the fourth row a beryl, an onyx, and a jasper. They shall be set in gold filigree. 21There shall be twelve stones with their names according to the names of the sons of Israel. They shall be like signets, each engraved with its name, for the twelve tribes. 22You shall make for the breastpiece twisted chains like cords, of pure gold.
